Recently purchased a second hand Grundig Box (so I can use its svideo output into my Media PC). Called Sky yesterday evening to pair my viewing card with the box, lady on the phone was very helpful and asked for the right information (from what I had read on doing this). She said it could take up to 4 hours for channels to be available. Tried to watch Sky this evening, and noticed the guide stops at channel 120. All channels above this are coming up as "Channel not available", yet I could access some subscription channels (e.g. Sky One on 106). When trying to access the Sky guide, it said "Searching for listings" for ages and did nothing. Turning the box off and on seemed to fix the issue - but any advice on what the issue could be?
